Hi fellas. I've got a 2010 Tiguan 4 motion 170bhp 2.0 tdi. It's got almost 90k on it.
I got it back in January and had the cam belt done and at the same time got them to change the oil in the 4 motion Haldex unit.
I've noticed for a little while that at motorway speeds there's a slight whining noise that starts becoming audible at 70, and rises in pitch upto about 90. It's speed related rather than revs. Yesterday it started getting louder, and more 'grindy' than whiny so I'm getting worried. You hear the noise under acceleration or constant throttle but It stops briefly when you take your foot off the gas. When it's under engine braking it comes back.
Any ideas? Gearbox? 4 motion? Just the oil in either of these or is something about to go bang?
